Torque for manifold-to-head nuts?
« on: May 15, 2003, 12:47:08 »
Hi All,

Does anyone have the "torque" required for attaching the manifolds to the head?
Thanks,

Hello Will,

Interesting question. This is not listed in the "Technical Data Booklet". I suspect that this is so since it is very difficult to get a straight shot onto some of these studs with a torque wrench. Any change in angle or use of any swival or universal joint will cause any torque reading to be incorrect. Be sure to use the proper washers and lock nuts. Do not tighten all at once. Do it in two or three passes. I use a 14mm swival socket and a nice long extension with a 3/8" drive ratchet handle.

Good point, Joe.
I remember now that it wasn't all that easy to get at them all for removal.
Thanks,
